Re: Re: Re: classloader issue with xercesImpl

    Hi,

For JOnAS 5.1.x, first locate the embedded properties file
In $JONAS_ROOT/lib/bootstrap/felix-launcher.jar, search 
org/ow2/jonas/launcher/felix/default-config.properties

Then copy this file for example in your 
JONAS_BASE/conf/felix-config.properties
Then modify the file by adding org.apache.xerces or other packages

Then run JOnAS with : 
-Djonas.felix.configuration.file=$JONAS_BASE/conf/felix-config.properties

For JOnAS 5.2.x, this file is configurable in JONAS_BASE/conf/osgi

Regards,

Florent
